NHTSA Complaint #11467581 — 2018 TESLA MODEL 3

Our model 3 was purchased with Tesla’s “full self driving (FSD)” software installed in 2018. Throughout our entire ownership period, whenever FSD is active, there are specific locations known to us - mostly at certain points on freeways - where the car will “phantom brake,” in other words suddenly decelerate the vehicle very rapidly and require *immediate* driver intervention. For instance, there is a freeway interchange ramp that passes under a bridge and doglegs to the left. The car will always phantom brake about 200 feet before it reaches the bridge. This has been happening for years, and we’ve reported this defect and this specific location to Tesla many times. There are other locations known to us as consistent phantom brake triggers, but there are of course times where this occurs when we are not expecting it as well, and that’s when it’s most dangerous. We believe it may have something to do with the car’s sensors when they sense certain shapes or objects while the road is also curving slightly, as this is the most common phantom brake scenario for us. Again, this has been happening since we purchased the car in 2018. It occurs randomly at least a few times a month, and it *always* occurs in certain locations.
